Gas content and gamma ray emission in the first galactic quadrant
Abstract
The Columbia CO survey and the Berkeley HI survey are compared with the COS-B gamma-ray survey. As a first step, the study is limited to the first galactic quadrant and to the high-energy gamma rays (E greater than 300 MeV). It is found that a simple model in which uniformly distributed cosmic rays interact with the interstellar gas can account for the observed gamma-ray emission. Furthermore if the contribution from point sources to the gamma-ray flux is significant, these sources have to have a galactic distribution similar to that of the CO emission.
